I'm sorry that your computer still will not work properly with the memory board. A technical representative from Unisys replaced your old memory board with a new one. George's computer now works fine. The problem I believe is that you motherboard has a Phonix BIOS rather than the standard 386 BIOS that normally comes with the Unisys. We can try to order more memory chips, but the problem will probably remain the same. I would recommend that you talk to someone about getting yourself a new 386-33MHZ machine that comes with 8 megabytes on board. If you write up the requirements that you need in a computer system, with the software you are currently running, you should be able to justify getting a new system.
